Consider a 1.2-m-high and 2-m-wide glass window with a thickness of 6 mm, thermal conductivity k = 0.78 W/m*K, and emissivity epsilon 0.9. The room and the walls that face the window are maintained at 25 deg-C, and the average temperature of the inner surface of the window is measured to be 5 deg-C. If the temperature of the outdoors is -5 deg-C,determine (a) the convection heat transfer coefficient on the inner surface of the window,(b) the rate of total heat transfer through the window.

Hint: calculate q dot convection, calculate qdot radiation, and sum. Hint: use FE handbook equations. Cengel Heat Transfer 5th edition, Homeworkquestion 9-48
